now on "maximum drama", our sunday feature. i'm dr. park deets, and i'm about to meet a man that i've never met before. he's already serving time for one homicide but yesterday he reached a plea agreement in which he admitted to killing six other women. part of the plea agreement is he had to tell the truth and the district attorney's office asked me to conduct this interview. >> a killer confessing to his crimes and a forensic psychiatrist delving into inside the mind of a convicted murder. >> they've granted us access to

videotape it. this was an effort to try to find out as much as we could about this man, his life his crimes. he's the one that set the limits on how far he would go. >> a man known as the i-5 strangler agrees to talk about his yims and to lead police on a search of his killing fields to avoid the death penalty. >> does it make you uncomfortable to have the cameras here? >> no. >> at what point in the process of taking your girl out do you know she's going to die? >> i haven't figured that one out yet. i don't know if it's half way down the road or when i'm doing it. i don't know why i picked these seven out of all that i picked up and let loose. >> do you think you understood why you did your crimes? >> no. >> are you curious? >> oh yeah. i don't know why i did them. >> would you like to know? >> throw it out there.

can evil ever be explained? well, if you're in the right place at the right time then perhaps it can. hi i'm jeff rossen. each episode of "maximum drama" brings you a compelling true story that plays out like a movie. in this hour we take you there, to that right time and place to put evil under the microscope as a criminal profiler matches wits with a serial killer. here's act one of profiling evil. >> at the san -- county courthouse, a killer arrives for questioning. however, this is not an ordinary investigation. this murder is about to take part in an extraordinary

interview. the man's name is roger kibby, better known as the i-5 strangler strangler. from 1977 until his capture in 1988, kibby terrorized the northern part of california with his killing spree. police say he was given the name the i-5 strangler because of where he disposed of the bodies of his first three victims. though he doesn't look intimidating now investigators say at this one time this man was capable of overpowering women, raping them and killing them at will. >> hi mr. kibby. can you shake hands? would it be all right to remove his handcuffs? >> sure. >> is that okay by you? >> kibby admits to killing seven women, but police say it's more. kibby is willing to talk to a

forensic psychiatrist if he can avoid the death penalty. despite a wealth of evidence against him, authorities are willing to offer kibby a plea deal. at 70 years of age, it's unlikely kibby will be executed before he dies of natural causes, and the plea deal ensures he will cooperate with authorities as they attempt to connect him to unsolved homicide. >> there kibby before we start i want to mejs a couple of things to you so it's all out on the table for you. one thing is i think you know i'm a forensic psychologist. >> in 2009 he pled guilty to six additional murders. part of the deal agreement with kibby is he would speak with us and also agree to speak with park deets about the crimes he committed. >> i never have been involved in a case where we filmed a thing such as this and i know you haven't either so we're exploring new territory here.

but part of what i want to make sure you understand there's no confidentiality, which is not the way it would be if you were seeing a doctor who was trying to help you. so i'm not here to help you. i'm not here to hurt you either. i'm here to ask questions, understand and try to shed some light on things. but that could end up helping you or hurting you. >> for more than three decades, park deets has interviewed some of the nation's most notorious killer such as joel rifken and jeffrey dahmer. his job is to get inside their heads, understand why they did what they did, so acts like theirs can be prevented in the future. >> my goals were both to assist law enforcement in answering some questions and also to be able to be able to understand his motivations and whether any

psychiatric disturbances played a part. kibby admits to killing 21-year-old lou llen burley but her remains have nevada been found. authorities hope that after this interview kibby will be convinced to lead them to her final resting place. >> there was a mystery that hbt been solved which is where were miss burley's remains? he had cooperated with investigators in trying to low cat the bodies and remains of over victims, but in her case despite his efforts to let them know where she was, she had never been found. >> lou ellen burley was a secretarial student when robert kibby tricked her into meeting him for a job interview. >> if i understand correctly, miss burleigh was your first homicide in 19 77. >> '77 first one.

>> start at the beginning of what was going on in your life that week and that day and how this came about. >> curiosity got me. i told the college and told the director i was moving company and made up all that crap. we got a warehouse over here and i would like to find somebody who can be office manager, and she wanted to know how many i wanted to look at. i said one, right now. i parked behind the theater at that time. she showed up and got out of her car and got in the van and we talked for a while. i told her i forgot my paper work and all that stuff. can i see you tomorrow? that's when i should have stopped. right there. i kept going. >> for park deets this is a key moment to understand. why did kibby keep going? what was his thinking that allowed him to follow through? to get answers dr. deets must ask the right questions in the

right order. >> now when you met her the first time thrks girl what were you thinking you might do? >> i might have been thinking that i get away with this. >> get away with what? >> get away with her. >> what were you going to do? were you going to rape her? >> have sex with her? >> yeah kidnap her, rape her, have sex, kill her. >> so from the beginning you were thinking about killing her? >> no. no. that never played into my mind. not until the second day. >> on the first day the idea was what? get a girlfriend date her? rape her? >> i don't know. >> kidnap her? >> maybe kidnap her, rape her. i never thought about killing. i don't believe that entered my mind until i had her down on the floor. she showed up on a sunday i believe, and got in the van and started talking, and i looked around and i told her, there's

my truck. she turned and looked. i reached out and grabbed a handful of hair on her head and pulled her down on the floor. we wrestled for a while until she pooped out, tied her up and i took off. where i was going, i had no idea. >> before hitz killing spree, roger kibbe was an avid sky diver with more than 4,000 jumps. once he began killing he used parachute cords to choke several of his victims. >> one of the interesting things about kibbe's background is his experience as a sky diver. what he no doubt discovered is that he could get a rush from jumping out of a plane. the fundamental biological difference is people who are psychopaths and those who aren't is psychopaths don't experience the normal level of anxiety that something scary is about to happen. once the scary thing has

happened they have a sudden rush of sensation, which is quite unfamiliar to them, and so it can become highly addictive to keep doing the things that evoke an emotion that's generally absent. >> so the potion you had her in was face down. at which point you tied her wrists together behind her back using a parachute cord. then you redated her bod dpi so the face is toward the rear of the van. >> no. let me back up. what i stupidly did, i got on the freeway to go back over the martinez bridge. and it hit me it's a toll. so to get her to shut up, i took the knife out and i put it to the back of her neck. i said don't scream. i'm coming down on this. >> coming up park deets discovers just how detached

roger kibbe is from the act of murder. >> you happen to remember what the first thing you did was when you got home? >> probably went to bed.

smplgts as part of the plea deal convicted killer roger kibbe, also known as the i-5 strangler has agreed to tell forensic psychologist dr. park dietz the truth about his crimes. he continues to tell how he killed his first victim, 21-year-old lou ellen burleigh. >> she was complaining they were too tight. i pulled over, loosed them up and kept on driving. where i was going, i had no clue. i could have went straight right, left wherever to find a place. i went right back up where i knew where to go. i knew how to get there. and that's where it happened. >> the land surrounding lake beresea is rough unforgiving lake terrain. >> what do you do? you put the van in park?

>> i parked the on a flat area. >> you pull the panties off or cut them off? >> i didn't cut the panties off. i cut the bra. i followed the road all the way down to the bottom of the canyon. you're drive uing you say? >> no, no. walking. the dirt road has a horseshoe shape in it. right there is a little canyon that goes up the hill. it's full of boulders, big boulders, and that's where she is today. >> and what happens when you're standing out there? >> i strangled her. >> how did you feel about killing her? >> i don't know. first time i ever did it. >> yeah, so i'm asking. >> i don't know. i felt bad later. i did it. thinking about it. while it was happening, blank mind. don't think of anything.

it's like a fog. >> was there any pleasure in the killing itself? >> no. none whatsoever. >> curiosity? >> maybe. it was an act that should have never happened. but i was too far into it. what do you do? >> i think the truth must be that at the time he had abducted her, had already raped her, there was no turning back. at that point his decision is which is more important? my continuing freedom or whether she dies. >> do you regret that as a rape? >> oh yeah. >> and would that be the first rape you ever committed? >> right. >> how did you feel about the rape part of it? >> how does anybody feel? good or bad? >> some people like it and they

keep doing it because it feels good. >> yeah. >> did you like it? >> i don't think so. i knew what i was doing was wrong, and if it's wrong you can't like it. >> a lot of people like doing things that are wrong. >> i'm one of them. >> the general theme of roger kibbe and other psycho sadistic serial killers because that's the category he's in is first an unusual sexual desire. to a man who is sexually sta disic the things that are sexiest, that are the turn on are control over the partner, the ability to have the partner do as he wishes. the ability to inflict pain or humiliation or suffering and ultimately the ability to control whether she lives or dies. >> if you had to rate that as a sexual experience from one to ten where ten is the best how

does it go? >> probably an eight. >> an eight? >> yeah because it's a forced act. act. >> i understand she's forced to do it. >> it takes two people to cooperate and tango. that's a ten. anything below that, below eight, almost has to be on her part i got a headache i don't want to do it. >> so having sex with this kidnapping victim be the equivalent of forcing your wife to have a headache. >> not good for her. probably good for me. >> when they asked you why you killed lou ellen burliegh your first murder victim, you said it was just to see if it could be done. >> yeah. >> what does that mean? >> you make a plan and carry it out, see if it can be done.

that's all. stack a bricks. >> you know there a lot of different plans a man can decide to make. could be can i get a job and hold it for six months. can i make my wife happy for a week? can i make myself save money? >> yeah. can i abduct and murder a wok? huh? where does that fit in with the plans a man might make? >> i don't know why i did what i did. to see if it could be done. i sid that before. >> do you see it as a challenge? >> so you give in the answer like why do you climb mount everest? >> because it's there. >> coming up investigators take roger kibbe to where he says he killed lou ellen burleigh and hopes they can find her remains.

inside the san joaquin county courthouse an extraordinary interview is taking place. part of convicted murder roger kibbe's plea deal calls for him to sit down with renowned forensic psychologist dr. park dietz for a tell-all conversation in hopes he will admit more than they know about it. >> one of the interested parties is detective vito -- who has been working the roger kibbe case for over ten years. >> when we had done our background on roger, we found he had taken a polly grooif in records to one of the crimes he did down in san diego. and they described kibbe at that time as being potentially one of the world's most dangerous men ever encountered.

he said the reason is because he had such a hatred for women. >> roger reese kibbe was born in 1941 and grew up outside san diego. kibbe tells investigators that his father now deceased was a naval officer who was rarely home and that as a young boy he was negative legislatelected by his mother, a person he refers toed a his dad's wife. >> i don't call her mother. my mom left for the navy and left his two boys home with his wife. i don't call her mother. i don't have one. my dad would come back from navy base late at night and two or three years old find me in the guard nn a pair of diaper ls. why i'm out there, i don't know. >> he recognized she was never good to him, wasn't warm didn't take care of him. beat him, abused him, neglected him, and that of course is a start of his hostility towards women.

>> going through elementary school couldn't read or write. going through junior high school, couldn't read or write. in the middle of the year i was asked to leave school because i couldn't read or write. dad went to the principal and was told that we just keep pushing him along and eventually they get it. well eventually never got around to me. >> what else do you remember about the way your mom treated you? >> always yelling. what did i do? there have been times when i even tried to get closer to her. because maybe i needed her and i wasn't getting her. no money to eat at the calf fearfeteria cafeteria. i wear t-shirts, not dress shirts. it was just bad all the way through. >> i do want to understand why your mom would neglect you so. you seem to think that's important and it seems important to me, too. >> i call it pretending to be a

housewife. >> did she give you any serious beatings? >> i think i was beaten several times. i can remember one christmas i got up and took a can of sugar an dumped it on the living room rug and took a car to make a road through it. i got beat pretty good for that. i got beat for not being home on time. >> did you have any friends as a child? >> i basically was a loner. in grade school i started stuttering really bad. i opened my mouth and nothing would come out. for about two years i never said more than one word. i was a loner all through life. >> it was in the early 1970s that he married his second wife. now in his early 30s kibbe works at a gas station and then manages a furniture store that eventually fails. kibbe tells investigators it doesn't tang long for he and

heir yet to begin arguing, which drives kibbe deeper into his killing rage. a monster in the outside world, he manages to keep his murderous actions a secret from his wife during their entire marriage. >> i had so many knives in my back because of her. she didn't cook. no breakfast. no lunch. one or two dinners i can remember. my god, i married my mother all over again. sild bring my checks home and stupidly give to her. i needed money for gas. i needed money to eat on. it wasn't there. i got pissed off at her several times. almost beat her. >> what would a perfect wife be like if you could design one to your specks? >> i don't think there is a perfect wife. >> besides trying to understand kibbe's past, dietz is also here to try to gather important information about how he killed. >> so is he saying he threw her

in? he didn't. he drug her down. >> police say they have dozens of open cases that closely resemble the kibbe murders. if dietz can get kibbe to admit certain things, he may well be responsible for other unsolved cases. >> can we talk about stephanie brown now? >> yeah. >> kibbe's second victim stephanie brown, was a 19-year-old student. this time his ruse was pretending to have car trouble when brown stopped to help him the side of the highway. police are especially interested in why stephanie brown like many of his other victims had clothes cut from her bod did i have. something kibbe refuses to admit doing. >> you said in the claim of the record that her skirt was cut. >> i was told her skirt was cut. they told me i cut. i told them you're full of

beans. i told her to take her clooets off. she took all her clothes off. all in one piece. she was sitting there. i untied her. i told her take your shoes off. take your skirt off. everything she took off, i told her to take off. there was never cutting. never. >> thoe kibbe is quick to deny cutting the clothes of his victim, the evidence at the crime scenes tells a very different story. one that park dietz says fits with kibbe's psychological profile. >> to cut the clothing can provide gratification to the offender without injurying the victim. so in a sense then cutting clothing is a kinder gentler means of exercising the sadistic impulse. >> i had told her to put her hair in a ponytail. i cut the ponytail off. is that a sign that i'm pissed off at my dad's wife? am i getting even with somebody? i don't know. i tossed her clothes in the

canal. they found the scissors in the canal. they found the skirt they said was cut in the canal. more cop lies. i never cut that skirt. somebody else had to do it. >> when roger was 15, 16 years of age, he was going to clothe lines and stealing womens clothing and bringing them back home and cutting them at that time. he will sit there and tell us about a rape he committed on a woman and tell us about the strangelation without any problem. when it came time for the clothes cutting he would back off. in his mind raping is okay. people do that. but cutting is very strange. >> she's the only girl i remember the name, stephanie brown. i don't remember the others. why do i remember her? i don't know. she was a bank teller. her and her girlfriend just bought a house. >> you learned all that from her? >> yeah, she told me a little bit.

and i did my thing. i strangled her and went home. it keeps getting easier and easier and easier to do it. >> what gets easier? >> killing. >> coming up, park dietz delves deeper into the mind of a killer. >> at what point in the process of taking a girl out do you know she's going to die? some people put everything into their work, their name on the door and their heart into their community.

roger koob bee, otherwise known as the i-5 strangler continues to tell dr. park dietz everything about the murders he's committed. >> when did you cut it? >> i usually take a piece that i had. >> it's a gruelling and at times horrific process. >> how about this? >> no. >> that's not you? >> i don't recognize it. >> and part of a plea agreement in which kibbe agrees to tell the truth about his crimes to avoid the death penalty. prosecutors want kibbe to confess so that victims' families learn the truth while giving kibbe a changs to opence to open up about unsolved cases. >> you understand this is an opportunity to confess to

anything without legal risk. >> right. and i told the officer i'm not going to confess to something i didn't do. i can't do that. >> nobody wants you to do that. >> i can't do that. >> but we would like you to confess to what you really did do. >> and you haven't got any others? >> no others. that's it. whether you want to believe me or not. >> at what point in the process of taking your girl out do you know she's going to die? >> i haven't figured that one out yet. because i don't know why. i don't know if it's right now. half way down the road or when i'm doing it. i don't know why i picked these seven out of all that i picked up and let loose. >> were there any occasions on which the strangelation itself

was a turn on for you? >> there's been times when i sat and thaurgtd about thought about it and i come up with the idea that while i was doing it my mind was a blank. someone took my mind. i would look off in another direction. look up at the stars if they're ready. i looked up and saw the big dipper. i just stared at the big dipper while i had my hands around her throat. i don't know how long it takes. to me it felt like it just took a few minutes. i've had people tell me it took much longer than that. >> in roger's mind strangulation was a gentler and kindser way to kill somebody. i think it was a power trip knowing that he had in his hands control of her life. he did tell stories of strangling women with his hands. he could feel the vocal cords inside their throats and he could squeeze and feel the life

go out of them. how many nights did you go look for a victim and find nobody? >> two or three nights maybe. >> so not a lot? >> not a lot, no. >> usually if you wanted one you found one? >> i'm usually 50/50. they're out there. but not what i wanted. other nights they stuck out like a sore thumb. they're willing to get into a car. that's your mistake. >> anything she could have done to avoided being pulled in the car in the first place? >> kept on driving until you get hauf the freeway where there are stores around way at the end of highway 12 where there's lights. where there's people. stop at a gas station. get directions. get back on the freeway. go home. and if someone did make the mistake of pulling over, maybe

to be a good samaritan to a motorist who has broken down how can she avoid being dragged into a car by the likes of you? >> not good. not good at all. >> what people should realize sh that kibbe is just the tip of the iceberg. there are more kibbes out there. when we did our investigation we were flooded with hundreds of possible leads in this case. some of these people are predators driving the roads among us. who live among us. kibbe made a comment that there was never a girl that was going to get from him once he decided to take her. so if anything else be wary. hopefully you're never in that situation. but i instructed my wife and my daughter, fight like hell. once he has you in that car, they were done. >> coming up the mystery of where lou ellen burliegh was

killed is finally solved. >> it was a miracle. i think i would go for the needle in the haystack over this. eliminate the odor. then we brought her family to our test facility to see if it worked.

a quick production note about profiling evil. film maker tom jennings told us the interview between dr. dietz and dr. kibbe lasted 12 hours, taped over a two-day period in a san joaquin county courthouse not far from kibbe's killing fields. now back to our story. >> the day after his court decreed interview with park dietz, roger kibbe is allowed out of his cell once again. investigators are hoping he will be able to find the spot where he killed lou ellen burliegh in the rural mountains surrounding

lake bariesa. >> i showed him the different aerial photos what they looked like in 1987 what they looked like then. so you could see how the area had changed. >> it went this away? >> it went this way. >> but you could have hit it with a rock. >> oh, yeah. you describe you had sex in the van and walked up over the top of the hill and went down. >> yeah. >> it's very overgrown now. >> we have been there several times with roger kibbe, even put him in a helicopter. we thought maybe if we put him

in a helicopter and he was able to see from above, he might be able to identify the location. >> that's what i'm looking for. i find that i can turn around and go back. >> we had him in 2009. so we did the same thing again. we drove up and down some roads. we got up and walked some roads. >> thoe kibugh kibbe described the spot in great detail once there he becomes confused. it's been more than three decades since the killing and nothing seems the same. >> there are no hills. it's all flat on top. there's dirt roads on top. >> see up there? does it look like it could be flat? >> things could change. but he's looking for specific items. so it was going to be extremely difficult for him to find that exact location. 32 years. this is our fourth time up here. we're never going to find that spot. >> if you stand here we can

look down into the valley. >> there was no other area that matched. either he was lying about where the homicide had occurred, or he didn't recognize the spot. but i knew her remains were in that area. they had to. >> what do you think the odds are? >> none. we're not going to find nothing here. we're done. this is definitely our last trip to this place. >> do you think he's jerking you around? >> i wonder. >> i don't. i think he would give this up if he could. >> i think he's probably trying. but in the back of my mind it's always been is he jerking us around? >> despite their efforts, investigators would not find the location on this day. it would take two more years for authorities to solve the mystery. the first break came in 2010 when napa county investigator

mike frooi found an ally, napa county deputy mike bartlett who is familiar with the case. bartlett was stationed there and he called me and said it's off season. there's not a lot going on. would you mind if i tried to find her? and i thought that was exactly what we needed. >> finally on a misty march morning of 2011. using information from the interview with park dietz and others they find the location. >> in 1977 when this occurred, roger kibbe parked his van up just over the other side of the bridge at the top of the hill. he led her over the top of the bridge and down this dirt road. this dirt road is presently 10, 12, 14 feet higher than it was then. so he said he was walking behind her, and he strangled her and then said he put her in the ravine from there.

after reading the transcripts and looking at the aerial photos i believe he murdered her right about here. >> once i got to this area and realized this isn't the way it looked back then and that the road was approximately ten feet lower with large boulders in the area, i felt this was it. after hiking around the area for approximately a month i started hiking the canyon down below us here. and within about 15 minutes i saw a white speck the size of a dime of a quarter in about six inches of water. i reached down into the water and pulled it up. as i was pulling it up i discovered it was a bone covered in mud and silt. as i examined it i realized it appeared to be a human hipbone. it was definitely a gratifying

experience. >> coming up park dietz gives his opinion of what drove the i--5 strangler to kill. >> for you to have sex was at least as important is weather she lived or died. ♪ hi dad. many years from now when the subaru is theirs... hey. you missed a spot. ...i'll look back on this day and laugh. love. it's what makes a subaru, a subaru.

>> no. >> are you curious? >> oh, yeah yeah. i don't know why i did them. >> do you think you have any secrets left? >> no everything's on the table. everything. >> yet there's some mysteries, things that don't fit, things that don't exist. >> was it my childhood, my upbringing. >> would you like to know? >> yeah, i'd like to know. >> i'm happy to tell you if you want to know. >> throw it out there. >> i don't think you have to be a psychiatrist to recognize that whatever happened between you and your mother has been the source of an enormous anger that's generalized beyond your mother that you've had a long-term disregard for the rules, a disrespect for authority. you've been willing to get even when you perceive that somebody

wronged you, you are willing to steal and to lie and to cheat. and that's are traits you've carried with you throughout your life i think. that set of traits in which you have anger and a willingness to break all the rules is a pretty familiar set of traits to the mental health professionals. what it was called at the time of your doing these things was sociopath or psychopath. and then it got the naamanty social personality disorder. there's a piece of you missing to be able to feel what other people feel and relate to their suffering. so it doesn't bother you the way it would others. you accept all this so far? >> yeah. >> and if your only crimes were forcible rapes of women, maybe hating women is enough to explain it but that isn't all you did, and it is a way to get even with women, to attack them

violently one after another. to convey to them that you think they're worthless, that they deserve no respect. the same way that your mom treated you. but to go further than that abduct them hold them captive, keep them under your control for a time and then ultimately strangle them after one or two orgasms on your end, that's more than just anger toward women on your end. as i was telling him my agreements, he was nodding in agreement. i wondered whether each step of the way whether he was going to stand up and walk out, whether he was going to get angry. what was going to happen. >> it's a fact for you to have an orgasm or sex was at least as important as whether she lived or died? >> yeah.

>> she didn't matter more than that? >> i have to agree with you. >> what would make sense of the whole story of abduction, rape captivity, binding, strangulation, homicides is if you've also got a special sexual interest in that area. and there are a bunch of clues that you do but you're saying not true to every one of them. the clues if believed that would explain this the cop who says when you were a kid, you stole some female clothes and cut it up. you cut female clothing and the story that you were as i kid, found tied up with women's clothes and claimed that you had been kidnapped and put there. the reason those would be so important, true is that cutting female clothing is a kind of substitute for cutting a woman. it's nonbloody, nonviolent

substitute for doing harm to a person, to cut their clothes. or to cut their photograph because those don't bleed. and nobody dies. and as ways to kill go i can see how you might think of strangulation as not as brutal as some of the other ways you might have killed them beating them to death or cutting them apart. today, when i ask you about all these crimes in detail you don't admit to the cutting of the clothing. and you deny cutting clothes when you were a kid. these are parts of the story you distance yourself from and there's a couple possible reasons of why you're denying those things to me and law enforcement. one possibility is that you don't remember. these things are too painful for you to remember and you've pushed them down. i don't really buy that but some people would.

another possibility is that these things are too shameful and too private and it's nobody's business. so you're not going to reveal that because you don't want people to think of you as being some kind of pervert. so i think that you've got some private fantasy life that involves tieing women up and keep ing keeping them where you'd like to hurt them but you'll make do with the substitute of cutting the clothing or cutting the ponytail, because you don't want to see yourself as that kind of person who cuts women up. that's what i think. you want to ask anything else? >> no. you're doing a good job. >> in the end he said you're doing a good job. so i think he accepted that what i said nailed it. >> roger kibbi avoided the death penalty. he's serving a life sentence

without the possibility of parole at san quentin state prison near san francisco.
